Data security at risk

Hello. My PC started to freeze frequently and the payment application didn't work correctly. After figuring it out, I realized that it was infected with a Trojan, but I don't know how to detect it.
Tell me what to do? And how to prevent my PC from getting infected with Trojans or other viruses in the future.

Hello. I had a similar situation and I found a blog https://gridinsoft.com/blogs/trojanwin32-wacatac/ that helped me. After reading, I understood what and how. Signs of a Trojan infection include unusual system behavior, slow performance, or unfamiliar programs running. If you suspect an infection, disconnect from the internet and run a full antivirus scan immediately. Quarantine or remove any detected threats, and review system processes for unknown entries. To prevent future infections, regularly back up important data, avoid suspicious downloads, and stay cautious when opening email attachments or links.

Businesses and individuals must stay alert and adapt to emerging threats through regular updates, strong authentication, and proactive monitoring. There’s a chance trwho security offers tools or insights that could help reduce these risks.
